GUSZcl ve f2 lfl'n INVENTOR,

A TTORNEV United States Patent DOOR STOP Gustave F. King, Seminole,0kla., assignor of one-half to Forrest D. King, Perry, Okla.

Application November 20, 1950, Serial No. 196,593 3 Claims. (Cl.292-339) wardly closing doors which are mounted on vertical axes,

and the swinging edges of which meet when closed, so that the doorscompletely fill or close the opening. Such vehicles have a flat panelwhich is approximately as wide as the van floor, and which has one endhingedly connected to the rear end of said floor by horizontallydisposed hinges. The panel is disposed on end in a vertical positionjust outside of the closed doors, when the truck is traveling. The freeswinging end of the panel may be swung rearwardly downward to form aloading or trucking ramp along which freight may be moved, in loading orunloading the van. The arrangement is such, that the panel may bedisposed at various downwardly sloping angles to the truck floor, whenfreight is to be moved therealong.

With the panel lowered, and with the doors swung open, there is no wayat the present time of eifectively anchoring the doors in their openpositions, with the result that they are at the mercy of the elements,and may be blown shut during freight movement into and out of the van.The doors of the van are normally restricted from blowing full open bychains (not shown) connecting the doors to the ramp.

The principal object of the present invention is to provide a door stopmechanism which will effectively hold the doors open when the ramp panelis in its lowered position.

Another object is to provide a door stop mechanism which is portable,and one of which may be removably anchored to each side edge of thelowered ramp panel, said mechanism having a door stop element rigidlyheld in the closing path of the swinging door.

A further object is to provide a stop mechanism which is sturdy inconstruction, and which is simple to install.

An additional object is to provide a device for the purposes set forth,which will not materially interfere with the movement of freight alongthe ramp.

Other objects will be apparent from the following description when takenin conjunction with the accom' panying single sheet of drawings,wherein:

Figure 1 is a perspective view showing a pair of the devices of thepresent invention operatively installed upon the ramp of a conventionalvan, the van and ramp being shown in dotted lines;

Figure 2 is a fragmentary perspective view, showing one of the devicesoperatively installed on the ramp of the van; and,

Figure 3 is a perspective view of one of the devices.

2,709,614 Patented May 31, 1955 In the drawings:

The reference numeral 1 indicates the rear end of a conventional movingvan, having a rear opening 2 adapted to be closed by two laterallyswinging doors 3 and 4. The van 1 has a floor 5 to the rear end of whichis hingedly mounted one end of a tail-gate 6, which is adapted to beswung downwardly from a normal vertical position behind the doors 3 and4 when they are in closed positions, to a downwardly sloping rearwardlyextending position as shown in Fig. 1. When in such a position, thetail-gate acts as a ramp along which freight may be moved into or out ofthe van. The ramp 6 may be disposed at various angles with relation tothe floor 5.

It may readily be seen that with the ramp 6 in its rearwardly extendingposition, and with the doors 3 and 4 in their open positions, there is aconsiderable open space between the upper surface of the ramp, and thelower edge of each door.

The device of the present invention is designed to be installed upon theramp to hold one of the doors in its open position, when the ramp is inuse. Since the ramp 6 is wider than the door opening 2, and since theramp may be disposed at various angles with relation to the bottom edgesof the two doors 3 and 4, a door stop installed upon the ramp must, inorder to be practical, be capable of adjustment to various positionswith relation to the upper surface and the side edge of the ramp. Withthese requirements in mind, the device of the present invention has beendesigned. It will be further understood that the ramp 6 may be connectedas by a chain (not shown) to the doors of the truck to restrict theiroutward movement.

The device, per se, of the present invention includes a fiat straightelongated strip 10 of strap-metal, having an integral downwardly turnedhook 11 at its outer end. The hook 11 is shaped toenvelop the side edgeportion of the ramp 6, when the strip 10 is resting flatly upon theupper surface of the ramp, as shown in Figs. 1 and 2.

The strip 10 has two spaced apart upwardly projecting parallel cars 12and 13 which are alignedly perforated transversely to receive a pivot orhinge pin 14. With one of its ends pivotally mounted on the pin 14,there is provided a stop element 15 which is also made of a piece ofstrap metal.

Intermediate its ends, the stop element 15 is also provided with twoparallel cars which are indicated by the reference numerals 22 and 23.The ears 22 and 23 are alignedly perforated transversely to receive apivot pin 24, which pivotally mounts one end of a strap-metal bracemember 25. The free end brace 25 is adapted to slide along the uppersurface of the strip 10 as the free end of the stop 15 is moved towardor away from the strip or base 10.

A stop shoulder 26 is provided between the two ears 12 and 13 to limitoutward swinging movement of the stop 15, so that it cannot be movedoutwardly beyond a position of perpendicularity to the strip 10.

Intermediate its ends, the upper surface: of the strip 10 is providedwith a plurality of spaced upwardly projecting lugs or deformities 27,28, and 29, against any selected one of which the free end of the brace25 may be engaged to hold the stop 15 in various upwardly projectingangles. The utility of these difierent lugs is illustrated in Figs. 2and 3 in which the lower end of the brace 25 is illustrated as abuttingdiiferent ones of the lugs.

It is pointed out that one of the devices is positioned upon the rampfor each of the doors 3 and 4, and that when in operative positions, thedevices do not interfere with the trucking or carrying freight along theramp 6.

Obviously the invention is susceptible to some change 3 or alterationwithout defeating its practicability, and I therefore do not wish to beconfined to the preferred embodiment shown in the drawings and describedherein, further than I am limited by the scope of the appended claims.

I claim:

1.. A door stop for the purposes set forth, including: a flat strip ofstrap-metal; a downwardly turned hook on one end of the strip; astraight strap-metal stop element having one end hingedly connected tothe upper surface of said strip intermediate the ends thereof, saidelement swingable from a horizontal to a vertical position; a straightstrap-metal brace having one of its ends hingedly connected to said stopelement, so that the free end of said brace may contact the uppersurface of said strip as'said element is moved on its hinge; means onthe said strip for selectively stopping movement of the said brace inone direction; means for limiting movement of said element upwardly awayfrom said strip.

2. A stop mechanism for horizontally swinging doors which are locatedabove a vertically tilted ramp, the combination including: a flatelongated base member adapted to lie flatly on said ramp with itsforward end beneath the open door and substantially even with one sideof the ramp; a downwardly turned hook carried by the forward end of saidbase member for clasping the edge of said ramp; an elongated strapelement having its lower end hingedly connected to the upper face ofsaid base member and swingable between horizontal and verticalpositions; and means for selectively anchoring said stop element invarious positions with relation to said base member.

3. In a door stop mechanism for limiting the inward travel of van doorswhere a ramp is utilized between truck and ground, the combinationincluding: a pair of substantially flat base members each having oneU-shaped end for clasping the edges of said ramp on either side andbeing provided with a series of outwardly facing notches on the upperface thereof; pivotal means on the upper faceof each said base memberproximate the said U-shaped ends thereof; and elongated stop memberhingedly connected to each of said pivotal means; and a brace hingedlyconnected to said stop members intermediate the ends thereof andadjustably engageable in the notches of said bases to vary the positionof said stop members between the horizontal and vertical.
